This is what I was trying to confirm. So a single light source with higher peak intensity is better at "pushing" light to the bottom of the tank...

It isn't better at "pushing" light to the bottom per se, it is simply brighter. A brighter light will be brighter than a dimmer light at any given distance from the bulb (assuming similar reflector/light extinction).
